Abstract: 985,691. Rotary moulding-machines. C. A. VOIGT. Nov. 28, 1962 [Dec. 18, 1961], No. 44951/62. Heading B5A. A circular carrier 3 is indexed to present a succession of peripherally mounted mould holders 6 to a ram 7, each holder having a tapered cavity, into which ram 7 pushes a prefilled. longitudinally split, tapered mould 13, and also having heating means 20. The arrangement is used in continuous production of rubber or other elastomeric compound items such as plugs and stoppers, which may include metal inserts. During one revolution of carrier 3, moulds 13 are retained in holders 6 by friction and vulcanization of mould contents is completed. The mould 13 is ejected from the uppermost holder 6, either by the ram or by a foot-operated plunger 14, before a fresh, filled mould is dropped in its place. Electric heaters 20 are powered from a distributer ring 23. The carrier may be supported by rollers to avoid strain on shaft 4 during pressing. The carrier may have arresting and locking means for accurate indexing, which may be effected by electric, hydraulic or manual means. Ram 7 may be manually or hydraulically powered. Plunger 14 may be hydraulically or electrically powered. Fig. 3, not shown, illustrates a horizontally rotating carrier.

A protective sheath of particles is formed on the inside wall of a cyclone by passing a magnetic field through the cyclone. The cyclone may be used for separating ore and gangue particles in suspension in a slurry. The magnetic particles may originate from the slurry or may be specially added thereto. The cyclone may be partly conical and partly cylindrical, or totally cylindrical. It may be made of two cylindrical parts, e.g. of rubber, stiffened by collars and connected by ties; the top of the two cylinders may be made in moulded halves connected by screws. In Fig. 1, a number of magnetic poles are placed near the exit 3 for the heavy and magnetic particles so as to provide a magnetic field converging towards the lateral wall. In Fig. 3, a coil 5, the central radial plane of which coincides with the begining of the exit duct 3, provides a magnetic field which converges downwards towards the duct. In Fig. 4, two coils 6, 7 spaced by a ring 8 of soft iron or ferromagnetic alloy are shown. Performance figures are given.

Abstract: 1,207,226. Refrigerators. ITT INDUSTRIES Inc. 26 Sept., 1968 [29 Sept., 1967], No. 45701/68. Heading F4H. A refrigerated display cabinet includes a first evaporator 45, 46, 47, a second evaporator 48 operating at a lower temperature than the first, and fans 52 for passing air sequentially over the first and second evaporators, the evaporators forming parts of separate refrigerating circuits. The first circuit employs CF 2 Cl 2  as refrigerant and the second CHF 2 Cl. The cooled air leaving the evaporators passes through a rear passage 68, which contains a plurality of deflectors arranged in a fan-like manner (Fig. 3, not shown), and then between louvres 65-67 which divide the divergent air streams into a plurality of substantially horizontal layers. The air passes over and into a storage area 69, then through an outlet 75 and a return duct 76 to the fan inlets; two fans, separated by a partition wall, are provided. The cabinet is opentopped and the front and rear walls have respective projections 57, 58 at their upper ends; projection 57 has two inclined surfaces 107, 108 and it is stated that the line of intersection 106 therebetween is arranged at the point of maximum temperature difference between adjacent air layers. The evaporators rest on a base member 39 formed with a drainage channel 40 and a groove 41 containing respective heating elements 43, 44, further heaters 50 being provided in the fin structure of the evaporators. A defrosting control thermostat 55 is provided adjacent the evaporators and together with a storage temperature control thermostat, the heating elements, and the compressor and fan motors is included in an electrical control circuit (Fig. 5, not shown) which includes a time delay thermal relay; the latter ensures that at startup both compressors are not simultaneously switched on. Defrost water from the drainage channel passes to a pan heated by one of the refrigeration circuits for evaporation. The condensing units of the two circuits are disposed at opposite ends of the cabinet beneath the cabinet beneath the storage space 69 which is of greater longitudinal extent than the chamber 38 which houses the evaporators and fans.
Patent GB-459179-A (GB)
Abstract: 459,179. Servomotor-control systems. SIEMENS APPARATE UND MASCHINEN GES., 4, Askanischer Platz, Berlin. July 4, 1935, No. 19123. Convention date, July 5, 1934. [Class 135] An automatic steering-control system, particularly for aircraft, comprises a controlling instrument N, a servomotor M in operative connection with a control surface R, and a regulating device st connected to both the controlling instrument N and the servomotor M by means of levers h, S, d. This system of levers is such that a movement of the controlling instrument produces a certain movement of the regulating device, whilst the restoring movement from the servomotor is increased to at least twice at the regulating device to produce a restoring movement of the regulating device equal to the amount which it was displaced by the controlling instrument. This arrangement enables deflections of the control surface up to half the normal maximum only to be utilized for the normal brief disturbances during flight thus allowing the rest of the possible deflection for displacing the zero position to compensate for any continuous lateral disturbance, such as for example, the failure of one of the motors of a multi-engined aircraft. This trimming displacement of the zero position of the control surface is permitted by a flexible-isodromic restoring device between the servomotor and the end B of the lever d. This device comprises a damping piston i<11> connected to the point B and working in a cylinder i<1> connected to the servomotor piston. The piston i<11> has small passages O1 across it so that the pressure of spring F attached to the end B of lever d produced by the restoring movement of the servomotor produces displacement relative to the cylinder i<1> and a different zero position of the control surface R. The piston ill is hollow and moves over another fixed piston till which normally maintains passages 02 closed, which passages however are opened in the event of a heavy disturbance requiring a large deflection of the control surface, to byepass the sides of the piston ill and allow the necessary deflection to be rapidly attained. Instead of the lever S, h for " stepping-up " the restoring movement from the servomotor suitable rack-and-pinion gearing may be employed.
